Edit an animation using the Animation wizard

You can use the Animation Wizard to do the following:

delete a range of frames

add one or more frames before or after a specific frame

resize animation length and preserve existing key values

To preserve key values when you remove frames, delete non-key frames. Deleting a key frame will delete the key value as well. You cannot delete a key frame in which any key value it contains is one of only two key values for a given property.
